My printer will not print and there is an mn1 on the printer brothers mfc-240c

SOURCE: printer keeps turning off,,,error message MN1 in lcd

I realise this is an old question but I recently had a similar issue with our MFC-5860CN not receiving faxes and displaying the "Mn1" code. As it turns out "Mn1" means the machine is set to manual receive and was therefore not automatically receiving faxes. You will need to locate the "Receive Mode" option in the menu and change it to "Fax Only" or "Fax / Tel". Unfortunately I dont know what could have caused the turning off and on that the OP mentioned. I'm a little late to the party but I hope this info can help someone else!

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks

SOURCE: paper jam in brother MFC 240C

Usually small pieces of paper are jammed at the print head area. Lift up the scanner and see if you can find the paper at the print head parking area, clear the paper . If you can't find the paper, remove the scanner cables, then the scanner. You will see 2 screws at the rear and one near the USB connection. Another 3 screws towards the front will remove the front panel. Under the panel remove 4 screws and the two panel harnesses. The is a speaker harness which you must remember to attach back later (most people don't remember to put back). Lift up the top cover and you can see the whole engine. Clear any pieces of paper that might be there.

Error code 36 is generally because of a paper jam that was not cleared. Remove the rear jam cover (the plastic cover in the back center of the machine)and the paper tray and check for any pieces of paper. Sometimes just a scrap will remain, but it's enough to cause the machine to not work.

Once you've replaced the covers, if the jam code does not reset, turn the machine off and then back on.
